10 Best Smart Toilet 2026 in the United States

The KOHLER NUMI 2.0 Comfort Height Smart Toilet is designed to offer a high level of comfort and advanced functionality. One of its standout features is the bidet functionality, which includes an adjustable stainless steel wand with options for water pressure, temperature, and spray shape. The heated seat and hands-free automatic lid and flush add to the convenience, ensuring a more hygienic and comfortable user experience. The deodorizer and self-cleaning functions, using UV light and electrolyzed water, help maintain cleanliness and freshness.

The motion-activated opening and closing of the lid, along with a quiet-close feature, prevent slamming and enhance ease of use. The dual flush system offers eco-friendly water usage options, with 0.8 or 1.0 gallons per flush, contributing to energy efficiency. The added height of the seat makes it more accessible for many adults, making sitting down and standing up easier. The compact, streamlined design ensures it fits well in various bathroom settings, and the elongated bowl provides extra comfort.

However, the requirement for professional installation may be a drawback for some users, as it adds to the overall cost and effort needed to set up the toilet. Additionally, being a high-end smart toilet, the price point might be steep for budget-conscious buyers. The KOHLER NUMI 2.0 is well-equipped with features that make it a strong contender in the smart toilet market, suitable for those looking for luxury and advanced functionality in their bathroom.

The Kohler K-5401-PA-0 Veil Comfort Height Skirted One-Piece Elongated Dual-Flush Intelligent Toilet offers a range of advanced features that provide a high level of comfort and convenience. Key strengths include its bidet functionality with adjustable temperature settings for a heated seat, front and rear wash modes, and an adjustable warm-air drying system. The automatic lid and flush, motion-activated cover, and touch-screen LCD remote control add to the ease of use.

Additionally, the self-cleaning function with UV light and electrolyzed water systems ensures hygiene by cleaning the wand surfaces automatically, and the deodorization system helps maintain a fresh environment. The tankless design and integrated personal cleansing contribute to its sleek, minimalist look, and the compact size makes it suitable for various bathroom spaces. The dual-flush technology, with options for full or partial flush, is also a notable feature for water efficiency.

However, the product has some drawbacks. At 114.6 pounds, it is relatively heavy, which could make installation more challenging. The price might also be on the higher side compared to other smart toilets, potentially making it less accessible to budget-conscious buyers. The Kohler Veil Intelligent Toilet is well-suited for individuals seeking a luxurious and technologically advanced toilet experience, emphasizing convenience, hygiene, and modern design.

The TOTO NEOREST NX1 smart toilet offers several features that align well with what buyers typically seek in a smart-toilet category. It includes an integrated bidet with front, rear, and soft wash modes, providing versatile cleaning options. The dual flush system with 1.0 and 0.8 gallons per flush options promotes water efficiency, and the Tornado Flush system is designed for powerful, thorough cleaning.

The ceramic surface is treated with CEFIONTECT glaze to help prevent waste buildup, which supports easier maintenance. The EWATER+® technology uses electrolyzed water to keep the bowl cleaner, contributing to hygiene. The seat is plastic, and given TOTO's reputation, the build quality is expected to be solid, though the product’s relatively high weight (141 pounds) means installation may require professional assistance.

This model is suitable for users seeking a reliable, water-efficient smart toilet with quality bidet functions and enhanced cleanliness but may not include some advanced automation and convenience features that other premium models offer.
